Recap

At Walter's former lab at Harvard, Walter and Astrid continue cutting into the amber and finally recover another video tape. Emerging, they play it and discover that Walter stored the tapes out of order. Walter on the tape gives them coordinates to a location in Pennsylvania. The real Walter doesn't remember anything about the location and according to the files, there's nothing in the area. He finds some hidden marijuana and sniffs it and then says that he should stay behind at the lab to regroup while the others indicate the location...
